I am reminded again how making friends as an adult is hard. Maybe it was hard as a kid, too - I can't remember having friends as a kid, really. It's strange that it's so difficult. One must assume that this is because other people must not want to make new friends, or because people are are very particular about the kinds of people they want to be friends with, even though with how hard it is to make friends, you'd think people would be more open to less ideal friendships.
I may have mentioned before about how even when it's possible to find an adult couple with kids our kid's ages, there may be weird things that make it difficult to relate. Some differences in religious belief, food tastes, politics, or economic status. Usually, we're the ones that don't go to church, eat weird food, and are - between the two of us - mostly liberal (even though I registered as a Republian after the 2016 election, which is a whole different topic), and that ends up being part of what turns people off somehow.
